.v useful Improvements in Valvesyand'I do hereby declare that thefollowing is a. full, clear, and exact description of the inventi on,which will 'enabl'otliers skilled in theartto whichit'apperta-ins tomake and use This invention relates to an improvement in valves and'pertain's-to an improvement adaptable to many forms'ofvalves such, forinstance, as check valves, angle. valves, globe valves and others.

h e invention also pertains-to improveseating faces thereof that in formoutside theva-lve-body sothat the grinding agent is kept outside the;Valvebody and not permittedto pass into and through the pipe system, theconstruction of' the valve being such that during the grinding theirsurfaces will be maintained in exactly the same relative position aswhen in 'place inthe valve-thus insuring that when replaced saidsurfaces will seat perfectly tight. Other objects will appear in thefollowing specification.

t is wellknown that'when a valve-seat or the valve restingth'ereonbecome damaged in anyway so asto permit the. fluid passing therethroughto leak between the ground faces it is necessary to regrind the surfacesin order that they may be made to seat perfectly andprevent suchleakage. It is also well known that in some ofthev older forms of valvesthe grinding andrethe emery, which cannot always be entirelyrcrnoved, iscarried along into'such' appa-. ratus by the fluid. It-is well known,also, that after a valve-seat has "ground a number of times it-isfinally rendered unfit 5ft)? further use: forobvious reasons'it'necessary'to remove the valve-body. from. th

making P p s,

'10 Din such a manner as to prevent leakage fectly and are not cut isinserted a tubular member or collar F of some length which constitutesthe valve-seat both of whose ends the upper and lower, are 'trued andproperly ground to receive the valve to be described presently. The saidcollar or seat has a circumferential flange G (Fig. 5) both of whoseupper and lower faces are turned off true and either of which is adaptedto rest upon the wall or partition way a fluid tight joint will bemaintained. However, if through any cause the surfaces are defaced so asto permit leakage between them, the plug U can be removed which willliberate the valve disk, the stem 1?, and the hood HH all of which canbe lifted from the valve-body .after which the valve seat F can beremoved. The surfaces of these two members w 'ch have been in contactcan them be ground to fit and then replaced in the valve after havingcleaned them thoroughly of the emery or other grinding agent employed,or, in place of grinding the surface the member whose surface has beendamaged can be inverted and then by replacing the parts the valve isready for use. It will be seen that by having both surfaces of the valvedisk and both ends of the valve-seat provided with ground surfaces fourchanges may be made before it becomes necessary to do any grinding orreseating in case the attendant has other more pressing duties to attendto the grinding and reseating being done when the pipe system is idle.After many regrindings and the valve-disk and seat have become too muchworn to be further used they may be replaced by new ones at a verynominal cost thereby malnng it unnecessary to-replace the valve-body byan entirely new one.

My form of valve is readily applicable to any kind of valve for anypurpose and besides the advantages enumerated there is the furtheradvantage that no internal projections are present in the valve such aswould retard the free passage of fluid therethrough and the thereof maybe utilized in angle valves, or valves of' any particular or peculiarshape and the invention contemplates any structure that will provide avalve having the between the collar and the said wall or part1- tion.Seated upon the flange G is a hood H (Fig. comprising a dome shapedupper portion; itslower portion consisting of a ring H which bears uponsaid flange G. The ring H and the dome are connected by legs J which.are spaced apart to provide the openings K for the passage of fluid.

The valve hereinbefore-referred to comprises a disk L, Fig. 3, providedwith an upper and lower flat face both properly ground torest upon thesurfaced top of the collar F, or seat, whereby the two form a fluidtight joint. At each side of the disk L is an extension M each having ahere at N whose axes are perpendicular to the plane of the disk and saidbores are provided to receive two vertical stems to act as guides, thelower one-being indicated by G and the upper one by P. Cast in thebottom of the valve-body is a boss Q, vertically bored at R forming asocket to receive said stem or'guide O. The dome H of the hoodhereinbefore mentioned is centrally bored at S and the guide or stem Preferred to extends therethrough and has a head T to rest upon saiddome. A plug U is provided for the top of the valve-body and has athreaded shank V to engage the threads of the extension C. Extendingcen- 40 trally through said plug is a set screw W having a rounded endadapted to seatin a depression 2 in thehead T of the guide or stem P.Said plug U is further provided with a threaded stem U at its top toreceive an internally threaded cap 3 to cover and protect the screw andprevent chance leakage. It will now be seen that the collar or seat F isfirmlyv and rigidly held in osition on the partition D by means 0 thehood HH' and remains permanently in position during the time the valveis assembled and in use and the means which holds said seat in positionthrough the hood is the set screw W described bearing upon the head T ofthe stem P.- w

The direction of flow of the fluid is indicated by the arrows. It passesthrough the seat F and lifts the disk L against the force of gravity,said disk being guided in its ver-' tical movements by the studs OP andhaving passed beneath the disk the fluid finds its outlet between t elegs J of the hood 1111'. .So long as the under face of the valve disk Land the upper face of the seat E fit peror damaged inany ing the valveand valve-seat when removed from the valve-body, the hood Hserves as anexcellent means of holding the members in their relative positions orthe positions they occupy while in service so that their surfaces willalways be ground accurately. The said hood serves. to centralize themembers during the grinding operation.

I amaware that the art shows a removable valve-seat held in placeagainst the underber held against it by a plug or closure in the bottomof the valve opposite the opening of-said diaphragm. Such anarrangement, however, involves abomplicatiori of structures and isexpensive besides having many parts to care for and keep tight forpreventing leakage. My device, however, does not depend upon and doesnot utilize 'a second closure since a single closure at the top of thevalve, through which, in one of its forms, the valve stem extends, isalso associated with the. means for holding the structure or equivalentseveral advantages outlined; While grindside of the diaphragm of a valveby a memy the extension of the top of the body,
